The bacterium most commonly colonizes the nostrils, although it can be found in other body sites.
Most research has focused on people who are newly colonized by the bacteria and has found that they are at substantial risk of subsequent infections.
In their paper, the authors suggest that the MRSA infection risk may be more closely tied to a hospitalization event than to the duration of carriage: "We submit that these high risks of MRSA infection among culture-positive prevalent carriers are not only preferentially detected because of hospitalization, but may in fact be incurred because of device related, wound related, and immunologic declines associated with a current illness." "One explanation for this may be that patients who have surgical wounds or intravenous lines may allow MRSA a route of entry and invasion that would not otherwise exist," added Dr. The authors caution that because this study was performed in a large tertiary care medical center, they may have studied a disproportionate number of critically ill patients who could be at a relatively higher risk for infection.
The results may not be generalizable to all patient settings. Huang is currently an assistant professor in the Division of Infectious Diseases at the University of California Irvine.
impetigo, boils, cellulitis, folliculitis, carbuncles, scalded skin syndrome, and abscesses, to life-threatening diseases such as pneumonia, meningitis, osteomyelitis, endocarditis, toxic shock syndrome, bacteremia, and sepsis. aureus autolysin, and in its absence or targeted inhibition, the daughter cells remain attached to one another and appear as clusters.) to water and oxygen.
Of these, 23 percent developed an MRSA infection within the year-long duration of this study. MRSA was identified as a contributor to the deaths of 14 of the patients.
Invasive methicillin-susceptible Staphylococcus aureus infection (MSSA) caused more infections and more deaths in hospitalized infants than invasive methicillin-resistant S.
Staphylococcus aureus (also known as golden staph) is a Gram-positive, round-shaped bacterium that is a member of the Firmicutes, and it is a member of the normal flora of the body, frequently found in the nose, respiratory tract, and on the skin.
This group includes the toxins TSST-1, and enterotoxin type B, which causes TSS associated with tampon use.
Toxic shock syndrome is characterized by fever, erythematous rash, low blood pressure, shock, multiple organ failure, and skin peeling.
